Find (fog)(x). f(x) = 2x
g(x) = x + 6
write your answer as a polynomial in simplest form.
(f•g)(x)=
Answer: (f•g)(x)=2x²+12x
Step-by-step explanation:
(f•g)(x) is the same as saying f(x)•g(x). Since we have f(x) and g(x), we can just multiply them together.
(f•g)(x)=2x(x+6) [distribute by FOIL]
(f•g)(x)=2x²+12x
Now, we know that (f•g)(x)=2x²+12x.
a. The formula F=95(K−273.15)+32 converts a temperature from Kelvin K to Fahrenheit F. Solve the formula for K.
K= this is solved
b. Convert 240∘ F to Kelvin K. Round your answer to the nearest hundredth.
240∘F ≈ __ Kelvin
The value of temperature in Kelvin K which has the value 240 degree in Fahrenheit F is 275 K.
How to convert a temperature from Kelvin?The formula to convert a temperature from Kelvin K to Fahrenheit F is,
[tex]F=95(K-273.15)+32[/tex]
Here, K is Kelvin and F is Fahrenheit.
Solve the formula for K in the following way,
[tex]F=95(K-273.15)+32[/tex]
Subtract 32 both side,
[tex]F-32=95(K-273.15)+32-32\\F-32=95(K-273.15)[/tex]
Divide, with 95, both side of equation,
[tex]\dfrac{F-32}{95}=(K-273.15)\\\dfrac{F-32}{95}=K-273.15\\\dfrac{F-32}{95}+273.15=K[/tex]
This is the solved equation for K.
To convert 240∘ F to Kelvin K, put the value in the formula given in above equation,
[tex]\dfrac{F-32}{95}+273.15=K\\\dfrac{240-32}{95}+273.15=K\\\dfrac{208}{95}+273.15=K\\2.12+273.15=K\\275.27=K\\K\approx 275[/tex]
Thus, the value of temperature in Kelvin K which has the value 240 degree in Fahrenheit F is 275 K.

What is 4,672.183 rounded to the nearest hundredth?
Answer:
The correct answer is 4,672.18.
Step-by-step explanation:
To solve this problem, we must look at the number we are given and determine what numbers are in which places. The 4 is in the thousands place, the 6 is in the hundreds place, the 7 is in the tens place, the 2 is in the ones place, the 1 is in the tenths place, the 8 is in the hundredths place, and the 3 is in the thousandths place.
The question asks us to round to the nearest hundredth, so this means that the number in the hundredths place should be the final digit. In the number given, the number 8 is in the hundredths place. Since the following digit (3) is less than 5, we round down and keep the 8 in the hundredths place. This makes our answer 4,672.18.

if someone weighs five times as much as someone else and the total weight of the two people is 132 pounds how much does each person weight
Answer:
The heavier person weighs 110 pounds, and the lighter person weighs 22 pounds.
Step-by-step explanation:
Let the weight of the lighter person be 1 unit.
The weight of the heavier person will be [tex]1\times 5=5u[/tex]
Total weight: [tex]1u+5u=6u[/tex]
6 units = 132
Divide 6:
[tex]1u=\frac{132}{6}[/tex]
[tex]1u=22[/tex]
The weight of the lighter person is 22 pounds.
Weight of the heavier person [tex]= 5\times 22=110[/tex]
The weight of the heavier person is 110 pounds.
Step-by-step explanation:
someone= 5x
someone + x= 132
5x + x = 132
6X=132
x=22
One person ("someone") weighs x× 5 = 110.
the other person ("x) weighs x = 22
Find k so that the line through(k-1,k+2) and (4,-1) is perpendicular to the line through (-3,2) and (2,5).
Answer:
k = 2
Step-by-step explanation:
Perpendicular lines have slopes opposite reciprocalFormula to find a slope:
m = (y₂-y₁)/(x₂-x₁)Coordinates of the first line:
(k-1, k+2) and (4, -1)Coordinates of the second line:
(-3, 2) and (2, 5)Slopes of the lines:
m₁ = (-1 - k -2)/(4 - k + 1) = - (k + 3)/-(k -5) = (k + 3)/ (k - 5)m₂ = (5 - 2)/ (2 + 3) = 3/5Since m₁ = - 1/m₂, we have:
(k + 3)/ (k - 5) = - 5/33(k + 3) = -5(k - 5)3k + 9 = - 5k + 253k + 5k = 25 - 98k = 16k = 2So the answer is 2
Which of the relations below are functions? Justify your answer.
d. For each graph above, state the domain and range.
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Delbert needs to mix a 20% acid solution with a 50% acid solution to create
100 milliliters of a 26 % solution. How many millileters of each solution must Delbert use?
Answer: Delbert must mix
_____ milliliters of the
20% solution and
_____ milliliters of the 50% solution.
Answer:
Step-by-step explanation:
26% is (26-20)/(50-20) = 6/30 = 1/5 of the way between 20% and 50%. That means 1/5 of the solution is 50% acid.
50% acid: 1/5 · 100 mL = 20 mL
20% acid: 100 mL -20 mL = 80 mL
Delbert must mix 80 mL of 20% acid and 20 mL of 50% acid.
_____
Maybe you'd like to see an equation. Let x represent the amount of 50% acid required. Then 100-x is the amount of 20% acid needed. The amount of acid in the mix is ...
0.50(x) +0.20(100 -x) = 0.26(100)
(0.50 -0.20)x = (0.26 -0.20)100 . . . . subtract 0.20(100)
x = (0.26 -0.20)/(0.50 -0.20)×100 = 20
This last expression should look a lot like the one we started with in this answer. It shows you how you can almost write down the answer to mixture problems without a lot of work.

show that the angles of an equalateral triangle are 60°each
Answer:
For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.
Since, we know, that the sum of all angles of any triangle be 180° .
Let each angle be a.
Thus,
Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.

Without solving, determine whether the equation has one solution, no solution, or infinitely many solutions. 6x+6=6(x+1)
Answer:
Infinite Solutions
Step-by-step explanation:
6x+6=6(x+1)
6x+6=6x+6
If both sides of the equations are equal, it will ALWAYS be infinite solutions:)
Answer:
Infinite solutions.
Step-by-step explanation:
You have to distribute the 6 to the x and the 1. You'll then realize that both sides have 6x+6, and since 6x-6x=0 and 6-6=0, If you solve this your answer would be 0=0 this means the problem has an infinite number of solutions.
Some triangles are drawn on squared paper. Which 3 triangles are congruent to one another?
Answer:
There are not 3 but only 2. The answer is below!
ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
